That's what happened when brothers Cabot, Hudson, and Barrett Phillips staged an elaborate video prank to convince their little sister, Millicent, that a zombie apocalypse had hit their hometown, Washington, D.C.

While driving home from her surgery, the prank unfolded when a fake Centers for Disease Control (CDC) warning came over the car radio, alerting citizens of "a viral outbreak" with "cases of high fever, nausea, death, and even cannibalism."
